Plex config via double NAT setup

[Ultra_Extreme]

Hey guys, ive got a quandry.

My network consiusts of a BT hub acting as a dumb modem, DHCP off, connected to a netgear Nighthawk R7000 Router which handles the network. Im struggling to get Plex to talk outside the LAN despite i believe port forwartding being correct

The BT hub is on IP 192.168.0.1
The nighthawk WAN IP is 192.168.0.2
The internal address range is 192.168.1.70-200
The server ip is 192.168.1.69

Is it possible? Ive set the bt hub to forward the external port 32400 to ip 192.168.0.2 and ive set the nighthawk to forward the same port to the server IP

Missing something?

BT Hubs are atrocious at port forwarding. I've dealt with probably all the different models of Home/BusinessHub and they all suck in one way or another. My favourite is the one that won't port forward unless you use the Web Admin panel to ping the device first. And even then it'll randomly stop port forwarding until you reboot the blooming router.

Which model Hub is it?

You say the hub is acting as a dumb modem, but is it not routing and doing NAT?

Also, is there a DMZ option on the Homehub and have you tried setting it to your Nighthawk, instead of forwarding a specific port on the hub? (You'll still need to forward the same port on the Nighthawk).

Another possible option, can you put another network interface on your server and hook it directly into the BT hub? Ugly, but if you're stuck with the hub, it might be the quickest and easiest solution if it works.

Presumably this is an ADSL connection? If it isn't leaving then HH in place makes no sense at all.

If you're going to leave a HH in place you'd probably be better off leaving it to do the routing and configure the R7000 as a WAP.

on the BT Hub set the Nighthawk to be in the DMZ - thus no need to set up specific port forwarding on the BT Hub at all.

Thus

port xyz --> BT Hub --> NigthHawk [port forward xyz --> plex server]

yeah this is what ive done and still no dice, ive also dmz'd my server through the nighthawk theoretically opening a channel all the way but nope i know what you mean about bthubs the business ones dont allow me to access my company servers running Windows server 2012 R2 either due to this issue

the network is fairly expansive crossing several buildings (the LAN anyway) so 'simple' solutions are unfeisable. I may look to swap the hub for a more configurable adsl gateway.

personally i think the issue may be the division of subnet from 0.1 to 1.1 but im not that techie with networking to understand it all. Could i in theory have the gateway on 1.1 and the router on 1.2? i guess i could?
